SAFETY APPLIANCE FOR CONTAINERS.

To all whom it may concem Be it known that I, SAMUEL N. NORTH, a citizenof the United States, residing at Mnncie, in the county of Delaware and6 State of Indiana, have invented certain new and useful Improvements inSafety Appliances for Containers, of which the following is aspecification.

This invention relates to improvements in safety appliances for the cansor other containers for gasolene or other hydro-carbon compounds orliquids, and has for one of its objects to provide a simply constructeddevice which will effectually prevent blazes 16 from igniting the gasesgenerated in the containers, and may be applied to cans or likecontainers of various kinds, automobile tanks, gasolene and stove tanks,reservoirs or other containers which are liable to come in directvcontact with. flames.

Another object of the invention is to sim plify and improve theconstruction and increase the efiiciency and utility of devices of thischaracter.

Another object of the invention is to provide a device of this characterwhich may be readily applied Without structural change to cans or othercontainers of various sizes.

Another object of the invention is to pro 0 vide a device of thischaracter which may be readily removed when the can is to be filled andwhich does not interfere with the ordinary uses of the can or othercontainer.

With these and other objects in View,

the invention consists in certain novel features of construction ashereafter shown and described and then specifically pointed out in'theclaims.

The improved device may be appliedto eans,,automobile tanks, gasolenestove tanks,

reservoirs or like containers, but is ,more particularly, ap licable tocans, and for the purpiose 'of illustration 'is shown thus 'applie andin the drawings enii loyed. to @5 illustrate the invention: v

cated in all the views of the drawings by the same reference characters.

The can to which the improved device is applied, is represented as awhole at 10 and is provided with the usual threaded nozzle 11, thenozzleextending outwardly as shown in Fig. 1, or turned inwardly asshown in Fig. 4, and it is not desired therefore to limit the improveddevice to nozzles of any particular shape or form. The improved devicewill preferably be of the screw form, but the improved device may bepermanently attached to the can as represented in Fig. 5.

The improved device comprises a guard or shell 13 of foraminous materialsuch as perforated metal, as shown in Fig. 1, or wire cloth as shown inFig. *i, but any suitable foramiuous material may be employed for thecage. The apertures or meshes of the cage are sniiiciently fine toprevent the pass sage of flame, but will permit liquids to freely pass.

When the improved device is applied to an outwardly directed threadednozzle 11, as shown in Fig. 1, the cage 13 is turned over at its upperend and thence directed downwardly with the downwardly directed portionthreaded as shown at 14. to engage over the threaded nozzle, and whenthe cage is applied to an inwardly directed nozzle as shown in Fig. 4,the upper portion of." the body of the cage is threaded as shown at 15to engage the threads of the nozzle and with the upper terminal of thecage directed outwardly in the form of a flange 16 to bear over theupper edge of the can top. When the turned-over form is em ployed asshown in Fig. 1, a gasket 17 of cork or other like material is lnsertedbetween the upper edge of the nozzle andthe turned-over portion of thecage, and when the form shown in Fig. 4 is employed the gasket 17 willbe inserted betweenthe flange 16 and'the body of the can. By this meansthe joint between the cage and the can is packed" and leakage of gas atthat point effectually prevented.

' When the cage 13 is permanently con nected to the can as shown in Fig.'5, of coursethe gasket 17 will not berequired. A cap device is employedover the upper open end ,of' the cage, and in the construe tion shown inFig.1, the cap comprises a horizontal-p0rtion 18 and athreaded dependingportion 19 which engages over the .i'ided "Withradii:

Bythis means i outlets of the can are provided with electusl safetyattachments and all danger of explosions prevented.

Having thus described the invention, What is claimed as new is:

1. In a. safety appliance for containers which the container is.provided with 5 th ceded extension, a cage of forarninous riel disposedto extend within the contamer, .d cage having it threaded extendisposedparallel and in spaced relait with respect to its body portion, saidwision being; received on the threaded -.sion of ti container. a capincluding led portion "which is eceived on led extension of the cage,said esp rmed with an open end, :1 plate threaded extension, e cage offoraminous materiel disposed to extend Within the container. said cagebeing formed with e threaded extension which embraces the cage and whichis received by the threaded-extension of the container, the extension ofthe container being; formed with en inwardly era the conical portionperforated. A

a closure for said open end and disposed flange, there being a packingdisposed between said flange and the extension of the cage, a caprovided with a threaded portion received on the extension of the cage,a plate constituting a stop interposed between said ca and the cage,said plate being formed with a central aperture, the cap being providedwith an opening which alines with the aperture formed in the plate, asprin disposed within the ca said spring being formed with curvedextensions which contact with the plate, a
